A policy saying “be careful” is not a guardrail. A guardrail is a limit the system cannot talk its way around.
Put the ceiling in code
Cap calls, tokens, retries, runtime, parallel workers, and dollars per run. Add a provider-level spend cap as a second wall. Repeated failure should shut the job down, not inspire more retries.
Route bulk, low-judgment work to cheaper models. A loop is always less expensive when the thing looping is cheap.
Make absence loud
A job can finish without error and still fail to produce the intended result. Monitor the outcome: the post exists, the file arrived, the queue contains the expected items, the customer record changed.
Keep logs and backups outside the file or system that could be damaged. Alert on missing outcomes, not only thrown errors.
Keep authority narrow
Use least-privilege credentials, a human approval queue, protected secrets, and a kill switch reachable in minutes. Separate drafting from publishing and proposing from purchasing.
Finally, rehearse the stop procedure. A control nobody can find under pressure is decoration.
